FIELD: radio engineering.
SUBSTANCE: invention relates to radio measurements and is intended for analysis of frequency-dependent radio circuits by their excitation with test signals. Measuring device comprises test signal generator with discretely changed frequency, pulse shaper, time interval former, pulse repetition frequency meter, and analogue-to-digital converter. Time interval former is a meter core, which by analysis of pulse sequence obtained from sinusoidal signal, selects the moments of time corresponding to achieved sinusoid maximum value.
EFFECT: technical result achieved when applying the invention consists in simplification of the meter.
